Application filed January 24, 1920. Serial No. 353,905.

To all whom it may concern Be it known that I, BEN F. Hannns'rr, acitizen of the United States, residing at St. Louis, Missouri, haveinvented a certain new and useful Improvement in Spring: EqualizerAttachments for Automobiles, of which the following is a full, clear,and exact description, such as will enable others skllled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of tlns specification, in which-Figure 1 is a front plan view of my improved spring equalizer attachmentfor automobiles.

This invention relates to a new and useful improvement in a springequalizer attachment for automobiles and consists in the formation ofthe bell-crank lever from pressed or wrought metal forming a part of aspring equalized. disclosed in an appl1cation filed by me of even dateherewlth.

The spring equalizer partially shown in Fig. 1 consists of the usualleaf sprlng 1 oi: a well known type of automobile (Ford) which issupported by a shackle 2 pivotally mounted in the upper end of abell-crank lever 4t fulcrumed on a reversed spring perch 3 mounted inthe axle 5 of the machine. 6 is a rod upon which is mounted the shockabsorbing means, said rod being duplicated on the opposite side of themachine so that when either front wheel is suddenly lifted, the shock orjar will not be transm tted to the leaf springs 1. The constructlons ofthe springs for absorbing these shocks or jars are not shown in thisappllcation, as they form the subject matter of the co-pendingapplication above referred to.

This invention relates particularly to the construction of thebell-crank lever which is preferably made of one piece "of stamped metalbent at each end upon itself to form a fulcrum and pivotal support forthe shackle (at its upper end), the lower end being bent upon itself toform a slot having a semicircular recess at its outer edge to receive asemicircular washer 7 arranged on the rod 6 so that said rod may have arocking movement relative to said fulcrum In Figs. 1 to l, 4: indicatesthe body portion of the bell-crank whose upper end is folded upon itselfso that it is provided with a jaw a perforated at 4;" to receive thepivot bolt 8 arranged in the upper end of the spring perch, said jaw lbeing connected to the main body portion of the blank by an inner endconnection 4. The lower end of the bell-crank lever is folded or bentupon itself, as at 4:, to form a slotted opening and the edges arerecessed at 4: to form a seat for the semicircular washer 7,the foldedlower end providing a slot through which the rod 6 passes.

I11 Figs. 5 and 6, I have shown a bell-crank lever and blank therefor,respectively, in which the upper end of the blank is formed with aprojection or leg 9 designed to fit in and be riveted or upset in anopening 9*, the lower end of the blank being folded upon itself asdescribed with reference to Figs. 1 to 4:.

In Figs. 7 and 8, the blank is formed so that there is a bridge wall 10extending over the top of the shackle and connecting the two side wallsof the bell-crank lever, the lower end being folded upon itself to formthe slotted edge recessed opening before described.

In Fig. 9, the blank is formed so that there is a bottom bridge wall 11connecting the two vertical walls of the upper end of the bell. cranklever, the lower end of said bellcrank lever being folded upon itself toform a recessed slotted seat for the semispherical head of the rod 6 asbefore described.

I claim:

,1. A spring equalizer attachment for automobiles in the form of a bellcrank lever consisting of an arm folded upon itself and recessed at itsedges to form a slotted opening through which an equalizer rod may pass,the other arm of said bell crank lever having its outer end formed toprovide-sepaspring shackle, the opposite end of said rated'jaws for theattachment of the spring blank being recessed at its edges and bentshackle. upon itself to form a slotted opening 10 2. A spring equalizerattachment for autothrough which an equalizer rod may pass. 5 mobilescomprising a blank bent upon itself In testimony whereof I hereuntoaffix my and provided with perforations to form a signature this 20thday of January 1920. fulcrum, and means of attachment for the BEN F.HAR-DESTY.
